Nebraska’s largest dam, Kingsley Dam on Lake McConaughy near Ogallala, is not in any danger of failure.
However, Central Nebraska Public Power and Irrigation officials say the 90-year-old structure needs a major resurfacing project to keep it safe in the future.
“We’re in good shape this year. We were about 60% of capacity,” said Kingsley Dam foreman Nathan Nielsen.
Nielsen scaled down the 50-foot face of the dam to show KETV what is causing him concern in the protective riprap.
“That material is dropped down. There’s some exposed smaller, smaller grain material up above,” Nielsen said.
The damage was caused in 2021 and 2022 by sustained high winds and waves when water levels at Lake McConaughy were considerably higher.
“You don’t want to leave it that way. You need to you need to get it repaired so that you’re not moving material. That’s that’s the goal. You don’t want to be moving material on your dam,” Nielsen said.
CNPPI District general manager Devin Brundage said the structure is safe.
